CLAY CARRIER,

Application filed June 9, 1926. Serial No. 114,752.:

This invention relates to clay carriers for use in connection with the doors of coke ovens and particularly to that classof such devices employing acar'provided with an upwardly or downwardly extending frame work in which is mounted a suitable elevator. The invention herein described and claimed has particular reference to the manner of arranging the hoisting rope and means for catching the car or movable platform in case of failure of the hoisting mechanism.

Referring to the drawings, Fig. 1 is a side elevation of the device; Fig. 2 is a top plan; Fig. 3 is a view looking from left to right in Fig. 1; Fig. 4 is a section taken upon the line l l of Fig. 1; Fig. 5 is a section taken upon the line 55 of Fig. 1;. Fig. 6 is a view of a portion of the upper mechanismlooking from right to left in Fig. 1; and Fig. 7 is a detailed view of one of the safety devices in engagement with one of. the racks.

i In the arrangement shown in the drawings,

,1 represents the ear or trolley frame which is mounted upon suitable axles Zcarrying supporting wheels'3 adapted to engage suitcoke oven.. Oneof these axles is provided with a suitabletransmission gearing 5 adapted to be operated by a motor 6 having abrake clrmn'?v adapted to be engaged bya brake band 'S'connected througha suitable lever 9, link 10 and lever 11. This lever-11 is connected to a suitable brake operating mechanism which will be described. I

The frame 1 is provided with a downwardly extending frame work comprising uprights 12 and 13' connected to a lower transverse frame work 14. Secured to the uprights '12 and 13 are rails 15, each of which is provided with a series of shoulders 16 extending as a group. Vertically movable between the uprights 12 and 13 and above the lower frame work. '14 is an elevator platform 17 having guides 18 engaging the sides of the rails 15.

' of the rails 15. adapted to move up and down between the The platform carries suitable side frames 19 extending upwardly and provided near their upper ends with guides 20 engaging the sides This elevator platform is rails 15 and to be supported inany desired position by the elevating mechanism.

The elevating mechanism comprises a motor 21 mounted on the framework and operatmg through suitable gearing 22 and a i the platform,

winding drum 23 whichreceives one-end of a cable 24. passing upwardly over a: sheave 25 and thence dowmvardlyalong the left side of the elevator and under a sheaveifld.

mounted upon a pin-'27 carried bya safety p v6O i latch frame. This safetyla tch frame comprises four'plates 28 ofsubstantiallythe'shape shown in Fi g. 7' mounted'in a gang; as a unit upon a pin 29 secured to the underside of the platform 17. v each of theselatchmembers and the latch There are two sheaves 26 in 1 members are all connectedby pin 30 at the outer corner as shown. .Each one of these latch units is pressed outwardly toward" the rail 15 by a spring 81' surrounding a rod32 pivoted to the latch unit atv 33 and passing through a suitable'guide34s. The spring31.

thrusts against an adjustablecollar 35;." The normal tendency ofeachone of thesev latch members is to move outward and to cause the p1n'30to engage one of the shoulders16.

There isa similar one of these latch members at the .oppositeside ofthe car and the eab1e 24 after passingund'er'the lefthand one passes under the righthandl one and thence up along theside ofthecar to the: upper-partof the framework where it passes around atransversely arranged sheave 36thence downward around: the other pair of sheaves 26 on the I safety latches and upward tothe point 37 Where it is dead c'nded in the frame. The

into a position to engage the shoulders 16 and prevent the platform from falling to the bottom. p

The motor 21 is controlled-bya. suitable controllerj38 operated by sheave 39 engaged b a controller cable 40 extending'down over. an idler 41 and overalower sh-eave42, one

part of this line being ataconvenient point to begrasped by the V The motor 6 1s controlledby a suitable con erated by a rope 45 passing over an idler 46 at the top and anidler 47 at the bottom, one

user when standing on troller 4E3 actuated by controller sheave 440prope 48 leadingdown along side of the car and engagingsheaveseE) and 50 thereon.

These sheaves are spaced and a sheave 51 carried by a bell crank brake lever 52 is adapted to engage the rope between the sheaves 49 and 50 and pull uponthe same producing an operation of a brake.

Advantages of our construction will be obvious. By passing the cable around and beneath the platform the overhead clearance of the platform is limited only by the trolley frame, a feature of particular importance in the use for which our invention is intended. Moreover, the latch plates and latch pin be ing of relatively light constructionthe latching operation is accomplished almost immediately with the initial emergency and the cable passing over a total of four latch operating sheaves a failure in any part of the cable is immediately. responded to by the latch mechanism. The cable itself is arranged in avery simple manner, passing from the hoist drum, beneath the elevator over an idling sheave and back beneath the elevator to a fixed position 111 the frame. By this arrangement a length of cable substantially bears only a quarter of the total elevator Weight so that the latch construction employed becomes of particular importance.

What we claim is:

'1]. In a clay carrier, a conveyor, a frame carriedthereby and including guide means, a platform movable along said guide means, a safety member movably mounted upon said platform, means urging said safety member a to platform supporting engagement with said guide means, a sheave carried by said safety member, and a platform supportlng cable passing around said sheave to maintain when supporting said platform, said safety member from said engagement.

2. In a clay carrier, a conveyor, a frame carried thereby and including notched elevator guides, a platform movable-in said guides, safety latches pivotally mounted upon said platform and spring urged to ehl gagement with sald guide notches, sheavgs ment with said notches in the adj acent of said guides, a plurality of sheaves carried by each of said latches, and a supporting cable passin under said platform around said sheaves whereby said latches are normally prevented from engaging said notches.

4. In a clay carrier, a conveyor, a frame carried thereby and including notched elevator guides, a platform movable in said guides, a safety latch pivotally mounted at each side of said platform and spring urged to engagement with said notches in the adjacent of said guides, a plurality of sheaves carried by each of said latches, and a support ing cable passing under said platformaround' said sheaves whereby said latches are normally prevented from engaging said notches, each of said latches comprising a plurality of spaced plate members maintained in assembly by members passing therethrough and forming respectively, latch pivoting means,

notch engaging means, sheave carrying means and spring connection means.

In testimony whereof we hereby affix our signatures.
